NetWorker: i backup dei client hanno esito negativo in caso di mancata corrispondenza dei peer tra client e storage node

I backup di un client del file system NetWorker hanno esito negativo con i seguenti errori osservati nei log delle sessioni:

181407:save: Step (1 of 7) for PID-87339: Save has been started on the client 'NETWORKER_CLIENT_NAME'.
174412:save: Step (2 of 7) for PID-87339: Running the backup on the client 'NETWORKER_CLIENT_NAME' for the save set 'SAVESET_NAME'.

Il dispositivo utilizzato per i backup è configurato tramite uno storage node NetWorker standalone. Il dispositivo non utilizza lo storage node integrato del server NetWorker.

La daemon.raw dello storage node NetWorker segnala problemi di mancata corrispondenza peer per lo stesso client:
